George & Patricia Walsh: $284K more in lifetime retirement income

The Situation

George and Patricia Walsh retired to Phoenix at 65 and 62 respectively. George had a $44,000 annual pension from his career in engineering; Patricia had none. Together they had accumulated $1.4M in traditional IRAs and were approaching the age where Required Minimum Distributions would begin.

Their plan was simple: take Social Security when Patricia turned 65 to add to the pension income, leave the IRA alone, and spend down as needed. It was the default plan — the one most retirees follow without analysis.

The Roth conversion opportunity had come up once in a conversation with their previous advisor, who dismissed it during the 2022 market downturn as 'bad timing.' What that advisor hadn't modelled was that the downturn actually made conversion cheaper — lower account values mean lower tax on the converted amount.

The Strategy

Social Security deferral to age 70. Every year Social Security is deferred past full retirement age (67 for George), the benefit increases by 8% per year. Deferring from 65 to 70 increases George's monthly benefit by 40%. At their life expectancy assumptions (George to 84, Patricia to 88), deferral generates $284,000 more in lifetime after-tax income than taking at 65. The breakeven age is 78 — and Patricia, as a survivor, benefits from the higher benefit for the rest of her life.

Roth conversion ladder. In the years between Patricia's retirement and Social Security beginning at 70, the Walshs have a five-year window of lower taxable income — only the pension and IRA withdrawals. We identified room to convert $60,000/year from their traditional IRA to Roth at a 22% federal rate — well below the 32% rate they'll face when RMDs begin. Over five years, $300,000 moves to Roth, generating a $680,000 Roth balance by age 80 after continued growth.

IRMAA elimination. Medicare's Income-Related Monthly Adjustment Amount (IRMAA) adds a surcharge to Part B and Part D premiums for higher-income retirees. The Walshs were over the threshold by approximately $14,000 — paying $3,564 per year in unnecessary surcharges. By managing the income carefully during conversion years — staying just below the $206,000 MAGI threshold for married couples — the surcharge is eliminated.

Estate optimization. Traditional IRA assets left to heirs are taxed as ordinary income when withdrawn — at the heirs' marginal rate. Roth IRA assets pass completely tax-free. By converting $300K of traditional IRA to Roth, the estate tax benefit to their two adult children is estimated at $235,000 in avoided income tax.

The Outcome

The combined value of Social Security deferral ($284K lifetime), IRMAA elimination ($53K over retirement), and Roth conversion estate benefit ($235K to heirs) represents over $570,000 in total financial improvement — from timing and structure decisions alone, with no change in investment strategy.

Patricia's summary: 'No one had ever shown us the Roth conversion math. It felt obvious once someone laid it out — we just needed someone to do it.' That's the consistent theme across every WealthFusions engagement. The strategies are known. What's rare is someone who assembles all of them into a coherent plan.
